POWER-TRANSM ITTER.

SPECIFICATION forming part of Letters Patent No. 303,094, dated August 5, 1884.

Application filed June 28, 1984.

2'0 a, whom it may concern.-

Be it known that I, HERBERT S. \VrLsoN, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented a new and useful Power- Transniitter, of which the following is a specification. a

This invention has forits object certain improvements on a former power-transmitter described in an application filed by me January 3, 1884, Serial No. 116,339.

In the drawings forming apart of this specification, Figure 1 is a plan elevation with parts broken away; Fig. 2, a broken plan View of the lower part of Fig. 1, looking from the right hand; Figs. 3 and 4, same as Fig. 2, showing changes in construction and arrangement.

In Fig. 1 is a supporting'frame, D D, having a cap at the upper end, in which the swiveled bearings a of the double-crank shaft u are located. With this double-crank shaft are connected swiveled reciprocating rods, the

lower ends of which rods are connected with the double-crank shaft f, having a stationary bearing in beams A. A A, whereby rotary motion is transmitted from the upper crank-shaft to the lower. These features, in general, are like those shown in the former application, above referred to. The pendent portion e of the swiveled bearing a is swiveled in the support 0, secured to the frame D D. This frame manner to the upper end, '2, of bar t.

D, in a windmill,would be termed a derrick, and with one end of the crank-shaft u the windwheel would be connected. The swiveled reciprocating rods consist of the half-round portions 0 c, which are looselylocatcd through an opening in the lower end of the pendent portion a and the parts it a a andJ a a. The upper end, a, of bar t is connected to the lower end of bar 0, said end as being perforated, and the bar 0 movably located therein. The lower end of bar a is connected in a swiveled Thus the positions of the crankshaft a may change by the rotation of theswiveled bearings a without interrupting the operation of the reciprocating rods and lower crankshaft, as shown in the prior application referred to. In said application the pitmen cl and 1' were pivotally connected with each end of the swivelcd reciprocating rods, and extended in like direc- (X0 model.)

tions from said points of connection to their respective crank-shafts of. In this construc tion the two sets of pitnicn (Z a" extend substantially in opposite directions from their points of connection with the reciprocating rods, and their movements during the operation are in substantial-1y opposite di recti ons-that is, when the pitrnan d, which is connected with the rod 0 t a a, moves down, the pitman 9", which forms connection with the lower end of said rod, moves upward, and the same with the pitmcn connecting with each end of the other rod, 0 t a ct. This is attained by the use of the centrally-pivoted levers B B. These levers may be pivoted exactly in the center of their two ends, or approximately so, according to the peculiar form and location. The lower ends of the reciprocating rods are pivotally connected with one end of the levers B B, and the upper ends of the pitrnen a" r are pivotally connected with The other ends of the levers B B. Ifpreferrcd, the levers B B maybe connected with the other ends of the reciprocating rods, and with the other pitrnan, d, in lieu of the arrangement in Fig. .l. The terms upper and lower are here used as referring to the position of the figures in the drawings, and not to fix the position of parts, which may vary in differently-located devices. To illustrate, the device may be located horizontally instead of vertically, as in Fig. 1. In this construction, the distance from the upper cranks 9V8]? the lines of the upper pitnian, reciprocating rods, pivoted levers B B, and the lower pitnian to the lower cranks is the same at any and all positions said parts take during the operation. This distance was the same in my former device referred to, and must be so in any practically operative transmitter of this class; but in the present device the general operation of parts is greatly facilitated, being more reliable and satisfactory, and I am enabled to locate the lower crank-shaft in many desirable positions otherwiseimpossible, and, as above stated, the pitinen at each end move in directions opposite to each other, which inequivalent forms of the pivoted levers B B.

Thus by changing the angle of the lever-arms each side of the point of pivoting, from the horizontal angles shown in Fig. 2, the point where the lovers B B are pivotally connected with the pitmen r 1' may be located at any point in a circle of which the lever-pivots form the axis, with a corresponding change in the position of the stationary crank-shaft.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is I I 1. In a mechanism for transmitting rotary motion from one crank-shaft to another, the combination, with the crank-shafts, reciproeating rods, and pivotally-connected pitmen, of the centrally-pivoted pivotally-connecting levers or their equivalents, whereby the pitmen of one set move in substantially an opposite direction to corresponding pitinen of the other set, for the objects set forth.

2. In a mechanism for transmitting rotary V motion from one crank-shaft to another, the

combination, with a crank-shaft having a swiveled bearing, a crank-shaft having a stationary bearing, swiveled reciprocating rods, and pivotally-connecting pitmen, of pivoted pivotally-connecting levers or their equivalents, whereby the pitmen of one set move in HERBERT S. WVILSON.
